A coated prosthetic implant and a method of forming a continuous coating of highly crystalline polymer over a prosthetic implant by means of passing particles of polymer through a high temperature plasma and subsequently depositing the molten particles over the implant surface. This invention is especially useful for coating polymer composite implants, such as a femoral insert for a hip joint prosthesis, with a coating of poly (aryl-ether-ketone).

Prosthetic implants with a highly crystalline coating

A method and apparatus for the fixation of bone fractures, limb lengthening, and the correction of deformities uses an improved composite plastic carbon fiber ring that is formed in a mold, or machined with a stepped end portion that allows half rings to be assembled in a common plane. The method can use a mold wherein multiple rings can be formed by stacking the rings with a Teflon layer therebetween and wherein circumferential braid reinforcement of carbon fiber adds strength at the circumferential inner and outer curved surfaces of the rings and half rings.

The invention provides biocompatible, corrosion-resistant prostheses and methods for producing these. A coating comprising a bismaleimide-triazine resin, a biocompatible plasticizer and optionally a thickener is applied to a prosthesis substrate and the resin is cured to provide a tightly adherent, biocompatible, corrosion-resistant coating. Radio-opaque materials, such as barium sulfate, may be included in the coating as well as bone ingrowth materials such as hydroxyapatite.
